Local Environmental Conditions
Nearby, close to home here, a stretch of hazel and willow lines the water, feeding some of spring's earliest pollen. This area, near this part of town, has well-kept lawns and ornamental trees in this park add their share of grass and ragweed pollen. Local readings for the surrounding area tend to follow this same general pattern.
Near the bank, hazel and willow lead the seasonal calendar, hitting its peak before most trees have even budded, around late winter into March. Late spring brings rising grass pollen that crests in June, before ragweed's late-summer surge carries the season into October. Daily pollen counts published for the wider region track this same seasonal rhythm closely.

Does pollen in Ontonagon come from nearby or far away?
Studies show that most pollen exposure (often 70–90%) comes from nearby sources, such as local trees and vegetation. A good pollen forecast therefore depends on accurately representing local vegetation. Pollen can travel long distances, but this usually matters only early in the season or during specific wind events.
Are pollen levels in Ontonagon based on measurements or forecasts?
Pollen data is often misunderstood. Most "pollen levels" are not real-time measurements, but forecasts.
Direct pollen measurements are typically delayed by 1-2 days because they require manual analysis. To show current conditions in Ontonagon, modern forecasts combine recent measurements, weather data, and information about local vegetation.
This allows us to estimate pollen levels for today and the coming days, not just report the past.

Understanding the Scale
The 0–100 scores represent risk levels, not direct measurements of pollen or air pollutant concentrations. Higher scores indicate higher risk. Pollen and air quality use different thresholds.
Pollen
| None | 0 | No or negligible risk of exposure. Pollen/mold exposure is expected to be minimal. |
| Low | 0-25 | Low risk of exposure. Small amounts of pollen or mold spores may be present. |
| Moderate | 25-50 | Moderate risk of exposure. Pollen/mold exposure is expected to be noticeable. |
| High | 50-75 | High risk of exposure. Elevated pollen/mold exposure is expected. |
| Very High | 75-100 | Very high risk of exposure. Pollen/mold exposure is expected to be at or near its highest levels. |
